Really!?? How does this tunnel loading/unloading thing work!? I've been building a layout, and I've been trying to get it so each factory/industry serves something else, and I end up with empty cars that "start over" again.... but I'm stuck on a few. Can you really just send them through a tunnel to be "emptied" or "loaded"? If so that is super duper cool! Please tell me more...
Diesel was one problem, because the Coal mine needs it.
